An ELT Glossary : Voicing
- Definition : An unvoiced sound is one produced without vibrating the vocal cords while the
sound is being made, while a voiced sound includes vibration of the vocal cords. If you touch your larynx at the same time as saying /m/ or /i/ you should be able to feel the vibration, whereas if you say /s/ or /ʃ/ you won't.
- Example : Many of the English consonants come in pairs which are identical in terms of place and manner of articulation - eg /p/ and /b/ are both bilabial plosive consonants -
they are made by momentarily blocking the airflow by closing the lips. But
/b/ is voiced - when it is made made the vocal cords are vibrated - while
/p/ is unvoiced.
